though they have been recognized in several European 

 countries. This is probably on account of the minute size of 

 the animals, and also because they belong to, or are nearly 

 allied to a class which has received but comparatively scanty 

 attention from most British naturalists. 



In May of this year I found several species of Pauropoda, 

 including four that I am able to identify with tolerable 

 certainty ; and as during that month I found Pauropoda 

 wherever I searched for them, I feel convinced that this group 

 is comparatively richly represented in our fauna. 



I at first thought of withholding these records until I had 

 amassed more material ; but as I see very little opportunity of 

 making a special study of the group for some years at least, 

 it would seem advisable to publish these notes. Panropiis 

 vtilgaris Hansen, and P. gracilis Hansen, are for the first 

 time recorded as British, and it is worth noting that all the 

 known British forms have occurred in our counties. 



I should mention that I have only had the opportunity of 

 consulting Lord Avebury's memoir and Hansen's paper. Dr. 

 Hansen, whom I had the pleasure of recently meeting in 

 Copenhagen, told me, however, that since he published his 

 monograph Silvestri had written on the Italian species, whilst 

 in a recent edition of " Acari, Myriop. et Scorp. hue. in Italia 

 rep.," Berlese had dealt more fully with the Pauropoda.
